Rapidly design and validate DC and high-frequency AC electrical network with multi-level of detail

The Electric Power Systems library enables to rapidly design and validate electrical power systems, comprising DC and AC high frequency (800Hz) distribution architecture with real time capabilities. This applies for energy balance architecture studies, transient studies, thermal management and coupling with cooling. Moreover, failure investigation can be performed with Fault triggering and re-configuration for fail safe/fail active architectures.

The EPSL covers the key components of an electrical power system at different levels of detail. The architectural level corresponds to "simple" phasor theory resulting in a quasi-static description of the system. The functional level of detail uses dynamic phasors to cover dynamic effects in the models. The level of detail can be selected via parameters in the components.
Additionally the EPSL enables the description of harmonics of the fundamental AC frequency, which can be either constant or variable. Currently the AC components are either single or three-phased, whereas other phase numbers would be straight-forward to be added due to the generic modeling approach of components.
